OBBUERGEN, Switzerland — Vice President JD Vance on Monday said his lengthy talks with senior Iranian officials in Switzerland created a "good foundation for a successful final deal" as they seek a permanent end to the war that the U.S. and Israel began in late February.
Vance and U.S. officials claimed progress on multiple fronts, including the establishment of "mechanisms" to ensure the Strait of Hormuz, a vital waterway for global energy shipments, stays open and to address fighting between Israel and Iranian-backed Hezbollah militants in southern Lebanon, where a ceasefire appeared to be holding.
The interim deal to end the fighting in Iran, signed last week by the leaders of the U.S. and Iran, sets a 60-day period for negotiations on key issues, including the future of Tehran's nuclear program amid concerns that Iran wants to use it for military purposes, a claim the country denies.
The vice president departed Switzerland as technical teams were still negotiating, and U.S. President Donald Trump talked up the efforts to keep the strait open to create “an oil gusher" as he stressed that the key to resolving the war was “respect” from Iran.
"As long as they respect us, I don’t want to use the word fear because that’s an inappropriate word, but as long as they respect us, we’re not going to have any trouble,” Trump said from the Oval Office.
Iran effectively closed the strait after the U.S. and Israel attacked on Feb. 28, causing fuel prices to skyrocket far beyond the region. The interim agreement to end the war was supposed to reopen the channel. Dozens of ships passed through it over the weekend, even though the main route is still mined and closed.
The lead negotiator of the Iranian delegation, Iran's parliamentary speaker, Mohammad Bagher Qalibaf, insisted on Monday that the Strait of Hormuz will be managed by Iran, but following international laws.
“Hopefully we can activate the strait again, in terms of passage, and bring prosperity back to regional and global economy," Qalibaf told Iranian state media on the plane on his way back from Switzerland.
Qalibaf and the Foreign Minister, Abbas Araghchi, arrived on Monday night in Oman where they met with the country’s Foreign Minister Badr al Busaidi to discuss the peace efforts and ensure safety navigation in the Strait of Hormuz.
The U.S. Treasury issued a 60-day license on Monday waiving sanctions on Iranian oil as part of the interim agreement. Notably, the license allows Iranian oil to be imported into the U.S., which has not imported significant amounts of Iranian oil since the 1990s.
Tanker traffic continued to pick up through the Strait of Hormuz. According to data and analytics firm Kpler, there were 71 confirmed transits over the weekend, with a peak of 35 crossings on Saturday. Before the war, 100 to 130 vessels passed through the strait each day.
Ships have been avoiding the central route to steer clear of mines, choosing instead to use the smaller northern route, which goes through Iranian waters, and the southern route, which goes through Omani waters. In the markets, Brent crude oil fell 3.2% to $77.52 per barrel, closer to its roughly $70 price from before the war. Benchmark U.S. crude oil fell 2.6% to $73.86 per barrel.
Trump was not in Switzerland but loomed large over talks
Trump did not attend what was dubbed the "Lake Lucerne Summit," but his presence certainly loomed large. The talks were jolted by statements from Trump, who, from thousands of miles away, fired off comments that offended the Iranians. But the mediation effort in Switzerland started Sunday and stretched into early Monday.
“We haven’t built the house, but we’ve laid a successful foundation to get to a good place for the American people,” Vance told reporters.
The vice president suggested that the U.S. could agree to unfreeze Iranian assets for purchases of U.S. soy, corn and wheat. He said Jared Kushner, Trump's son-in-law and one of the lead U.S. negotiators, came up with the idea with officials from Qatar.
Vance said Qatar would have approval over the process, and Iranian money that would be accessible as sanctions were lifted would buy American products "for the benefit of the Iranian people.”
Iran, which has pressed for the unfreezing of billions of dollars in assets, has not commented on the idea. The assets have been frozen over years of sanctions, banking restrictions and legal disputes imposed by the U.S. and international community.
Iranians agree there was progress on their top issue
Shortly after the Iran war began on Feb. 28, Hezbollah and Israel also went to war, with Hezbollah firing rockets and drones at civilian communities in northern Israel and Israel seizing large swaths of southern Lebanon. Iran has insisted that addressing the fighting in Lebanon is a critical component of any deal to end the wider conflict.
Iran noted “major progress” to end the fighting in Lebanon and called that the first real test of the negotiations.
Foreign Minister Araghchi wrote on X that mediators delivered "major progress to end the Lebanon War." But he said the first "real test" of negotiations would be whether the mechanism succeeds in halting the fighting between Israel and Hezbollah.
Neither Israel nor Hezbollah is a signatory to the U.S.-Iran deal.
But as of Monday evening in the Middle East, the ceasefire between Israel and Hezbollah appeared to be holding.
“We have not detected trajectories from either side since yesterday,” said Tilak Pokharel, a spokesperson for the U.N. peacekeeping force in southern Lebanon known as UNIFIL.
Airspace violations and Israeli military movements continued, Pokharel said.
Hezbollah has not announced any attacks on Israeli forces since Saturday.
The lull in fighting in Lebanon is the longest since the latest Israel-Hezbollah war began on March 2.
